A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Industrial strategies to minimize glycerol formation in ethanol fermentation by conventional Saccharomyces cerevisiae

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Industrial ethanol production faces the challenge of balancing metabolic efficiency with the minimization of byproducts such as glycerol, whose formation is intensified by osmotic, thermal, oxidative, and nutritional stresses. In the literature, two main approaches stand out for modulating its synthesis: the use of genetically modified strains

Insights into the Ecological Roles and Evolution of Methyl-Coenzyme M Reductase-Containing Hot Spring Archaea [PDF]

, 2019
Several recent studies have shown the presence of genes for the key enzyme associated with archaeal methane/alkane metabolism, methyl-coenzyme M reductase (Mcr), in metagenome-assembled genomes (MAGs) divergent to existing archaeal lineages.

Nano‐networks via reaction‐induced self‐assembly coordinate spatiotemporal multi‐drug delivery for acute kidney injury therapy

BMEMat, EarlyView.
Multifunctional nano‐networks (NNWs) are prepared via reaction‐induced self‐assembly (RISA) of spermidine (SPD), epigallocatechin gallate (EGCG), 2‐formylphenylboronic acid (2‐FPBA), and deferoxamine (DFO) through dynamic iminoboronate bonds. These NNWs leverage the oxidative AKI microenvironment to trigger disintegration, enabling site‐specific ...

NH‐Sulfilimine Synthesis Catalyzed by Nonheme Iron(II) Complex

ChemistryEurope, EarlyView.
Sulfilimines are emerging as valuable functional group in modern medicinal chemistry. Yet, their catalytic preparation is underexplored compared to sulfoximines. Here, the iron‐catalyzed synthesis of 14 examples of unprotected sulfilimines in good yields, under aerobic atmosphere and at room temperature, is described.

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

Chemistry – A European Journal, EarlyView.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
